To prepare the thermal glass we use the well studied Kob-Anderson binary mixture model [1]}. Our model consists of \(N\)  classical point particles confined in a three-dimensional simulation box in the \(NVT\)  ensemble. We choose a binary Lennard-Jones (LJ) mixture of particles which are labeled as A and B, and their number ratio is \(80:20\) . For simplicity, the mass of both types of particles \(m\)  is taken to be the same and equal to unity. The interaction potential for a pair of particles has the following form,
\(U_{\alpha \beta }(r) &=& 4\epsilon _{\alpha \beta }\Big [\Big (\frac{\sigma _{\alpha \beta }}{r}\Big )^{12} - \Big (\frac{\sigma _{\alpha \beta }}{r}\Big )^{6} + A_0 \nonumber \\ &+& A_1\Big (\frac{r}{\sigma _{\alpha \beta }}\Big ) + A_2\Big (\frac{r}{\sigma _{\alpha \beta }}\Big )^2\Big ] \ , r\le r_{cut} \nonumber \\&=& 0 \,~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ {r>r_{cut}}, \)
